An Excessive Heat Warning will be in effect Tuesday until 8 p.m. for Ashley, Chicot, Desha, Drew and Lincoln counties. Dangerously hot conditions with daytime heat index values as high as 112 to 115 degrees are expected.
Other parts of the state, including other Southeast Arkansas counties, remain under a Heat Advisory with expected heat index values of 105 to 110.
Heat index values will remain high for Wednesday afternoon with values approaching 110 degrees in southeastern sections of the state. Temperatures will gradually cool later this week and into the weekend though chances for thunderstorms increase over time each afternoon into early next week.
Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities.
Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.
Take extra precautions if you work or spend time outside. When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments.
Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 911.
